We have all heard the term from someone that our Psoas is tight.  So what exactly is the Psoas responsible for?

The psoas major attaches to the spine at T12 through L4 and then dowm into the femur in the area of the groin.  This muscle is mainly thought of as  a  hip flexor, the truth of the matter is that it is also much more.

1)It is a hip flexor when the foot is off of the ground.

2) It is an external rotator of the Femur.

3) Depending on positioning, it can also internally rotate the femur.

4) It is a adductor of the leg.  (This means that is pulls your leg toward the midline of your body.)

5) It is a lateral flexor of the lumbar spine.

6) It can assist in hip hike

7)The psoas on the right side contracts to allow you to rotate your torso to the right.

8) It assist in creating a lordosis of the lumbar spine region.

As you can clearly see, if the psoas muscle becomes inhibited it can play an major role in decreasing Range of Motion throughout other areas of movement.
